STA-LL-FLOOR.

SPECIFICATION forming part of Letters t me No. 528,849, dated November 6, 1 894.

Application filed July 21, 189?:- Serial No- 518,232. (No model.)

To all whom it may concern.-

Be it known that we, WILLIAM A. BROWN and SAMUEL G. BROWN, citizens of the United States, residing at Lynn, Essex county, Massachusetts,have jointlyinvented certain new and useful Improvements in Stall-Floors, of which the following is a specification.

Our improvements are in the class of drainage systems for stables illustrated in the patent No. 502,221, which was issued to the said Samuel G. Brown on the 25th day of July, 1893, to which reference may be made for structural details not herein specifically described.

Modern sanitary requirements, which call for frequent washing out or flushing of stalldrains,equally forbid any spillage or leakage of fecal mattersinto the space underneath the stall-floor. This latter requirementimportant in all cases-is absolutely imperative for those stables of the better class which have offices or other rooms on the floor immediately beneath them.

A leading feature of our present improve or elevated wasteway. Fig. 3 is a perspective view of the said sealing-frame. Fig. 4, shows the outlet-screen in axial section. Fig. 5, shows a composite floor with sealing-device on our plan.

1, may represent sills, beams or headers which support any suitable foundation, such as wooden planking 2. Such sills, beams or headers also serve to support the vertically flanged and seamless drain-pan or drip-pan 3-3'. Supported upon the drain-pan 3-3 is a removable slatted flap or floor-piece 4, which,when in place,--rests on the drain pan, in the manner shown, so as to occupy the floor-opening and to stand at the same level with the rest of the stall-floor; also flush with the stallfioor, and surrounding the flap or floor piece,is the joint-sealing frame 5,-preferably of cast or wrought iron-but which may be of wood. The dimensions of these parts are such as to present a deep narrow trough or trench 6,--known, in thisspecification as the sealing-trough between the frame 5, and the pan-flange 3. The cavity formed by the sealing-trough and the space above the foundation-planking is filled with a downward integral extension 7 of a course 7 of asphalt, concrete, kosmocrete, beton, or other suitable cement to the level of the slatted floor-piece and sealing-frame, with the result of creating an absolutely closed joint at the line of junction of the drain-pan flange with the stall-floor opening, thus making any escape of liquid impossible except at the proper placev of discharge, 8. For the more certain retention of the asphalt filling within the sealing-trough, the frame 5, may have any form of roughened or irregular exterior, as, for example, it may have a number of projections 9. In addition to the utilities above cited, the frame 5, servesin the act of laying down the asphalt while in its plastic conditionas a gage or mold, and, after the bed of asphalt has become set,-the same frame protects the edge of the bed from liability to be chipped and pulverized by the animals hoofs. The said frame furthermore, enables proper inclosure of the slatted floorpiece and its convenient attachment, by means of hinges 10.

The discharge-orifice 8, located at the lowest part of the drain-pan, is protected by a dome-shaped screen 11, which has several ranks of orifices 12, and acentral large opening presented by a stand-pipe 13, which constitutes an elevated overflow or wasteway.

In the usual conditions, the lowest series of orifices serve to carry off the liquids but, should these orifices become clogged, ven tage takes place through those higher up. In the event of the choking up of all the orifices 12, the liquid accumulations, together with the suspended solids, pass off through the large elevated overflow or wasteway 13. The elevated ICO wasteway further serves as a handle for re moval of the screen for any purpose.

From the above illustration of our inven- Hon-selected because of proven efficiency deviation may be made in minor details to suit diverse preferences or requirements. For example: where a wooden wearing surface is preferred, the stall-floor may have the composite construction shown in Fig. 5, in which the asphalt is used in any desired lesser quantity snfiicient to fill the sealing-trough and the floor proper consists of wooden planking 14, secured in any proper manner such as by spiking to the foundation timbers in the manner shown or to cleats that have been embedded in the asphalt while the latter is in the plastic condition. In some situations, the foundation floor may be of other material than timber, such, for example, as masonry or boiler-plate. The shed of the drip-pan may be such as to drain to any part within the marginal rim.

\Ve claim as new andof our invention-- 1. The combination of the supports, the flooring located on the supports, the drainpan having a discharge opening and an upwardly extending peripheral flange seated in the supports beneath the edge of the flooring, the removable slatted floor-piece located in the drain-pan, and the intermediate frame surrounding the floor-piece and forming a sealing trough inside of the flange and the edge of the flooring and a course of cement located on the flooring flush with the frame, havinga downward integral extension filling the sealing trough; substantially as described.

2. The combination of the supports, the flooring located on the supports, the drainpan having a discharge opening and upwardly extending peripheral flange, the removable slatted floor piece located in the drain-pan, the intermediate frame surrounding the floorpiece and forming a sealing trough, a course of cement located on the flooring flush with the frame, having a downward integral extension filling the sealing trough, and the dome-shaped screen located over the discharge-opening and having a surmounting stand-pipe; substantially as described.

8. The combination of the floor 2, the seamless-drain-pau 3 supported on the floor and having an upwardly extending flange 3', the frame 5 seated within and projecting above the pan and forming (in connection Withthe pan and its flange) a sealing trough 6, the bed 7 of cement which surrounds the frame, and has a downward integral extension 7 filling and closing the sealingtrough, and the wearing floor 14E superimposed upon and covering the bed 7; substantially as and for the purpose set forth.
